Is This Any Way To Go Back To The Moon?

NASA should shed lesser priorities to achieve a 2024 moon landing, Op Ed, Doug Cooke

"NASA should focus major new development on an integrated lander/ascent vehicle launched on an SLS 1B. With Orion launched on a separate SLS, the lunar landing would be achieved with these two flights, and at most one commercial launch with additional fuel. This is a much simpler approach with a significantly higher probability of success."

Keith's note: On one hand Boeing consultant Doug Cooke wants to kill Gateway because it adds complexity and increases the number of points where a failure could derail the Moon 2024 thing. No argument there. He then goes on to push for the SLS variant that features Boeing's Exploration Upper Stage (EUS) - and requires more SLS flights. The net result is likely going to be a wash when it comes to cost. And given the SLS program's chronic inability to do anything on time or within budget, there are likely to be SLS and EUS issues that will also cause the 2024 deadline to be missed.

Or, NASA could adopt an open source, multi-path, modular approach relying on existing commercial launchers, and standard interfaces. And if you have to build SLS then use it as a cargo vehicle only. If a large effort is to be mounted on the Moon and cislunar space then propellant depots should be thrown into the mix. Relying on SLS in an architecture for sending Americans and cargo back to the Moon is, itself, the prime risk factor so long as it remains in the critical path - whether it is 2024 or 2028 that you are aiming for.

Its anyone's guess right now as to how the election will turn out. As we've all seen, when a new Administration arrives they have a strong tendency to fiddle with the previous Administration's space goals. Adopting flexibility in terms of launch vehicles and space assets is the best way to assure that something will survive a potential transition and put people on the Moon. But sticking with a program that is utterly reliant upon SLS - a program that gets more expensive and extends its target date with every passing day - is not the best way to assure that we'll be heading back to the Moon. And if this whole Moon thing is supposedly being done to get humans to Mars sooner, then the need to be more flexible and creative is underscored.

Then again Jeff and Elon may just make this whole NASA Moon/Mars thing moot.
